The study was conducted over a five week period. During Week One of the study, all participants worked in their usual workcenters which consisted of traditional fixed height desks in both cubicle and private office environments. During that week, the volunteers were outfitted with VitalConnect’s HealthPatch wearable cardiac patch sensor devices, which continuously monitor a variety of key biomarkers including ECG and heart rate. These sensor devices were integrated by Fujitsu Laboratories into the Sprout platform, thereby providing continuous storage of these biomarker data streams for establishing a baseline for each participant. The Sprout also enabled storage of participant stress values, based on real-time analysis of the ECG data stream. All participants also underwent basic health screenings for weight and body mass index (BMI) and took blood tests to establish starting levels for HDL & LDL cholesterol, fasting glucose levels and other key biomarkers.
Leading into Week Two, fixed height work surfaces were replaced with the Workrite Sierra Electric Workcenters and the Workrite Willow or Willow Dual adjustable monitor arms. These workcenters were instrumented with tablets running the Fujitsu Sprout; the accelerometer and camera sensors in the tablets were used to algorithmically assess the height and state of the workcenter. Beginning on Monday of Week Two, participants returned to work and began using their new workcenter equipment after receiving basic operating instructions and an overview of proper ergonomic equipment positioning.
During the next four weeks, each individual desk was monitored using periodic photographic data and real-time tablet accelerometry data to determine when participants were present and how much time was spent in the sitting or standing position. This real-time data collection and analysis was made possible through the use of Fujitsu’s Sprout mobile real-time data aggregation and analysis platform, running on Android tablets affixed to the work surfaces. In addition, all data streams (including those made available through the cardiac patches) were synchronized with the cloud in real-time for visualization and real-time on-site triage of any data collection issues.
During Week Five of the study, participants were patched and monitored again so physiological measurements could be taken and compared to the baseline data established during Week One of the study. Both biometric results and self-reporting results are included in this report. Participants completed a paper questionnaire at the beginning and end of the study.
At the end of the study, all participants were given a choice to keep their height adjustable work center or have their fixed height desks reinstalled.All participants chose to keep their height adjustable workcenters.
